The invention may be briefly described as comprising operating meohanism enolosed in n easing and preferubly ineluding one or more sets of plunetary gearing eonneeted to drive i roteting member such as a sheave which in turn is conneeted to the door 01' door sections to be lifted. In one embodi- 1nent of the imention tl1e driving member carried by a easing detachably eonnected to the gearing oasing ab we mentioned and this driving 1nember may eonsist of a motor 01 of a sprocket wheel adapted to be rotated manually. In another form of the invention, nmnely, tl1at shown in Figs. 5-7 the planetary gearing is driven by spur gearing Wl1lCl1 in turn is actnated manually.

.l"eierring first to the enibodiment 013' the invention shown in Figs. 1 inclusive, I have sl1own a portion 10 of a building having 1 door opening 11 therein and a door comprising a plnrality of seetions suoh as a lOWG1 section 12 end en upper seetion 13 adapted to close the opening.

The seetion 12 of the door carries rollers 1 adapted to engage tracks 15 as the door is pulled upwardly and the section 13 has eenneeted thereto links 1G the opposite ends of which are connected at 17 to braekers 18 aflixed 01 seeured te the wall 10. The links 10 operete in 2. manner te cause the door seeti0ns te be swung inwardly alfter the lmver sectien 12 has been raised te re gister with the upper section.

T he invention abont te be described relntes particularly t0 0perating 1nechanis1n i*0r lifting and swinging doors 0 the type abeve 0nt1ined. In the form of the inen tien shewn in Figs. 1 -l. this operating meehanism is carried by 1 casing 20 sec1nred hy 1001s 21 to the wall 10, preferably slighly abeve and at 0ne side 0f the door as illustrated in The cssing 20 has monnied therein a plnrality 01 sets A end B of plahetary gearing uithough 0ne set n1ay be hsed when the required gear rednction will allmv it.

In Fig. 1 I have sh0wn (1 casing 24 se- (ured in one end of the casing 20 and heus ing a shait 25 en W111C11 is pinned er etherwise fixedly secnred a sprocket wheel 26 u.daped te be nmnually rotated. The shaft 25 extends throngxh he rear wall of the casin g 21 and into the casing 20 and a spur genr 27 01? the planetary set A is monnted en the inner end of the shz1ft 25. The geen 27 meshes With planet gears 28 of the set and the gears 28 als0 mesh with a staiionary ring geur 29. The p1anet gears 28 are monnted en pins secured 1:0 l spider 30 and the spider has secured thereto 01 forming a part thereof. a spur gear 32 arranged te turn freel v xvith the spider en (1 shaft 31. The spnr geur 32 1neshes with planet genre 33 whieh a]s0 mesh with the ring geur 29 and are carried by a spider 34. The spider 34 is pinned 01 otherwise fixedly :1taehed te lhe shaft 31 m0unted in bear ings 36. A double clrain pocket sheave 37 is keyed 21s sh0wn at- 38 er otherwise fixedly secnred to the shaft 31 and is hereiere driven thereby.

The sheave 37 rnay he connecled in A11)" suitable 1nanner to the door sectiens and in the ferm of the invention shown counterweighting 1nechanism is prmided and is used in cenneetion wich the geur drive abeve described. This connterweighting mechans1n comprises l counterweight 40 which suspended Fr0n1 a double sheave er txv0 single sheaves 1-1. A pair of chains 42 ex tends arennd the donb1e sheave or twe single shezwes 11 and aronnd lhe donble peelei; sheave 37. Each of: these chains is fixedl v seenred as shown at 43 at 0ne end und hs che ether end secnred at any snit uhle p0int sneh as 14: to the lower (1001 seetion 12. 1n the case 01' the single sec- ;i0n door. 1110 l0wer end of the chain W0nld be similarly secnred 0 a suitable point on the doer secion.

As sh0wn in Fig. 3 0ne of the chains 4-2 extends acr0ss the wa1l above the opening 11 and around 2111 idler 15 and downwardly thereirom te soms sueh point as 4A adjacent the le\ver end 01" the side edge of the door secion 12. As the two chains +1-2 inay stretch nnequa1ly u turn bnekle 46 is pre- .ided in one of the chains 0r eqnalizing t:he lengthS of the chains.

The constrnction shown in Figs. 1-4 inclnsive nm he eperated manually by re tating the sprocket \vheel 2G 01 ii desired 21 ensing 21 snch 21s shovvn in Fig. 1 may he suhstinted 1 01 the casing 24 and 1neans sneh as 21 meter 50 enclosed within or attached te rhe casing 24 may be connected 1I0 drive the shai't 25 and spur geur 27 carried therehy. Spnr geer 27 drives plsne: gears 23 and thereby retates the spider 20 cennected te shaft 25. In ether words eiher i 1nanna1 or a motor drive n1ay he used and one of these drives 1nay he snhstitnted '0r the ether without dis nnmtling. taking down er otherwise dis- .rrnging the transmission gearing. The ennsiruetien shewn in Figs. 14- inclnsive eperntes as follows.

ijlssnming that the hand drive is niilized the sprocket 20 Will be retated 1nannally hy pulling en a chnin carried thereby. As a sprocket is rofated the drive Will he transnritted through gears 27 and 28 of the. first sei 0ii plunetary gearing A 1nd hence threugh the spider 30 te the second set of plunetary geuring including gears 32 and 33 and he spider 34. The ring geur 29 eperetes in the nsual manner in connection with the gears 28 and 33.

The spider 34 drives the shaft 31 and he sheuve 37 is driven by the shait. The sheave 37 is connected in the. mnnner above deseribed to the door and the rofation ef the sheuve wil] cause the door te be raised in the nsual mannen 1n Figs. 57 inclusive, I have illustrated anether embodinient of the door operatinp; nieehinisni. As the door parus in Figs. and 7 are eenstructed in the same 1nanner as these shmvn in die preceding fignres like parts are indicated by corresponding referenee -hnracters in b0th sets of fignres. In this form 01 the invention the casing G0 seeured to the Wall of the building us h hols 00 above the opening and houses z1 01 planetary gearing C. As shown in iig. u plse er casing n1en1ber 60 is also secnred te the Will, by bolts G1 intermediue the easing 00 and the \Vll1. '1he jenrnnled in plate er me1nber G0 hzwng niennted al 0ne end u sprecket wheel 32 h\ 111021115 of which rhe shat may be rntr.ted. '1heshnf 01 als) carries 1 spnr nee (53 vvh eh 1neshes with spnr geer 64 und the geur (34-. h:1s formed integral therewith er seeured thereto l spur geer G5.

1he geer n1eshes with planet gears 66 eerried by A spider 67 and the spider is lreyed 1S shown t 68 01 otherwise fixedly secured to the shaft 69 also journaled in plate 60. The shaft 69 extends through the gears 65 and 64 and through the rear end of the casing and has secured to its rear end a pocket sheave 70. The sheat-e 70 is connected hy a ehain 71 to one side edge of the lower door section 12 adjueent the, lower end thereof as shown zit 72.

The opposite end. of the shaft 69 is connected by a holt G9 to a coupling 75 the opposite end of whieh is oonnected by means of u belt located and placed during the erection and thus permitting sliding and rotary adjustrnent o the shaft 76 to take np variations in the center to center distance of the lifting ehans and in their length. The gap 77 between the ends of the shafts 69 and 76 also permits the removal of the outer casing or casng 60 without disturbing the counterweight mechenism or other parts of the door er operating mechanisrn therefor. By I'GIIIOVB the bolts 60 and the bolts 69 and 80, the eonpling 7 5 may be moved along the shaft 76 and the casing 60 and gears therein may be rernoved for repair or for any other purpose without dismantling the door, links or coiniterbilincing mechanisrn.

A pocket sheave 78 is secured to the end of the shmt 76 and is connected to the other edge of the door section 12 by a chain 79 The door seetion in Fig. 7 is shown as swung from the vertieal t0 inelined position loy links 16 pivoted at 81 to the upper door seetion and at 82 on the easing 60, concentrie with the shaft 69.

The eonstruotion shown in Figs. 5-7 inclnshe operates as follows. The sprooket G2 is rotated manually thereloy rotating the gears 63 and 64 and the central geer 65 of the planetary gearing set C. Although I have shown only one set of planetary gearing, it will be readily understood that a plurality of sets of this gearing may be used as shown in the form of the invention previously described and illustrated by Fig. 1. The drive is transmitted from the gear 65 tl1rough planet gears 66 and throngh spider 67 to the slmft 69. The rotation of the slmft 69 \Vill operate the doors loy means of the el1a.in connection to the sheave 70 zuid to the sheave 7 8 carried by the shaft 7G whieh is connected With the shaft 69 by the eonpling 75.

Frorn the foregoing specification it will be clen that the door operating meehanism is simple, compact and will oooupy 21 minin1n1n un1onnt of space. Further1nore t Will be evident tlmt the units can be assembled at the shop nnd een be delivered and erected without dismantling. This Wi1l save ex pense and also insure the proper adjust1nent of the "arious gea1s and other eooperating pnrts.

Althongh certnin speoilio en1bod1nents of the invention have been illustrated and deseribed, it will be nnderstood that the invention is eupuble o :further modification end thut urther changes in the construetion and in the arrzu1gen1ent o the various eooperating parts may be made without departing from the spirit or scope of the in vention as expressed in the following elaims.
